Use RabbitMQ as the messaging solution.
Load an application template and create an application from it.
Delete the application and the template.
Load a new template.
Create a new application from this template.
The creation fails. A stack trace appears in the logs.

For some reason (to determine), the DM's exchange was deleted. At least, it should have been created (again) by the new messaging client. And for the same reason, it is not possible to delete the application then (messaging exception). The only option is to restart the DM...
This is really annoying. :angry:
